Standards and Evaluation pilots are almost like test pilots.. They are expected to stick with their aircraft perhaps a little longer than normal. However, if a pilot has no outside reference to the horizon (the rain storm he was in), and his sensors/instruments are deemed unreliable, I would have done the same thing. Its one thing to lose a jet, which can be replaced - its another to lose a pilot where countless hours of training have been invested ... Sucks for him, but at least he is still flying and gets the pick of the littler for his next assignment. I would assume he will do another tour and then retire. People will be "funny" around him going forward and he will not enjoy the camaraderie that he has grown used to in the Corps.
